On the other hand, the POS terminal 10 transmits power transmission request information to the peripheral device 20 when power is stopped from the power cable. The peripheral device 20 is associated with the POS terminal 10 by pairing. The POS terminal 10 charges the power transmitted from the peripheral device 20 via the non-contact power receiving unit 18b. That is, when a power failure occurs, the POS terminal 10 charges the secondary battery 16 with the power supplied from the peripheral device 20. Then, the POS terminal 10 can execute a shutdown process using the charged power. Therefore, the POS terminal 10 can maintain the activation of the POS terminal 10 during a period from the stop of the power supplied from the power cable until the secondary battery 16 is charged with the power transmitted from the peripheral device 20. What is necessary is just to provide the secondary battery 16 of capacity | capacitance. Therefore, the POS system 1 of the present embodiment can reduce the size of the secondary battery 16 as compared with the conventional case.
